Abstract
A separator is provided for separating portions from elongate casings stuffed with food mass, in particular for separating sausages from alginate casings stuffed with sausage meat. The separator includes two circulating conveyor members spaced apart from one another and drivable by at least one drive element, and at least one crimping member arranged on each conveyor member. It is proposed that the legs of a crimping portion of the crimping members are curved on their side facing an adjacently arranged second crimping member in operation, such that the stuffed casing is first constricted in a constriction region with displacement of the food mass and then severed, producing a desirable shape for the portions separated.
Description
- This application claims priority to German Application No. 10 2021 112 517.0, filed May 12, 2021. The above-mentioned patent application is incorporated herein by reference in its entirety.
- This application relates to a separator for separating portions from elongate casings stuffed with food mass, in particular for separating sausages from alginate casings stuffed with sausage meat.
- In prior art devices and methods for producing sausages, synthetic or natural gut casings are stuffed with a pasty mass such as meat emulsion with the help of a pump or a stuffing machine and portioned with the help of a portioning device, and subsequently divided into single sausages; other types of mass are also stuffed into a casing in the same manner. In most cases, the mass is provided by a stuffing machine that has a feeding hopper and a feed pump.
- In one kind of prior art method, a twist point which separates the individual sausage portions from one another is produced in the gut casing by a twist linking unit and the portioning device. In another type of portioning device according to the prior art, sausages are not twisted off, but the casing is coextruded in liquid form around a strand of the food mass. The casing, which in many cases is made of alginate, solidifies. After producing such a stuffed casing, and during further conveying, pre-crimping members pierce the casing stuffed with food mass and displace both the food mass and the casing, thus creating a constriction point. For that purpose, laterally projecting pre-crimping members are arranged on the conveyor members at intervals approximately equal to the length of a sausage and converge to form pairs with a pre-crimping member that in operation is opposite on the adjacent spaced-apart conveyor member, thereby constricting the mass in the stuffed casing, together with the casing, in the region of a constriction point.
- The sausage portion is then divided with the aid of crimping members. The crimping members are likewise on conveyor members at intervals approximately equal to the length of a sausage. The crimping members known from the prior art have an attachment portion for attaching the crimping members to the conveyor member and a flat crimping portion arranged adjacent the attachment portion. The crimping portion has two legs that open to form a base portion. Although the design of the crimping portions just described ensures that the sausage portions are reliably separated, there is still room for improvement.
- For example, it has occasionally been observed in practice that the ends of the portions or sausages are not fully formed at the separation points. For example, the sausage ends may have a shape which is not round and which can then be further shaped in a subsequent cooking process by the sausage shrinking. Such an uneven or non-rounded shape of the sausage ends is sometimes perceived by the consumer as undesirable.
- As a result, it would be desirable to develop a separator of the kind initially specified in such a way that the disadvantages encountered in the prior art are eliminated as far as possible. In particular, a device is to be specified that allows the ends of the portions to be given a round and uniform shape.
- These and other technical objects and problems are addressed by the embodiments provided in this invention. To this end, the separator according to embodiments of the invention achieve this at least in part by having the legs be curved on their side facing an adjacently arranged second crimping member in operation, such that the stuffed casing is first constricted in a constriction region with displacement of the mass, and then severed.
- The invention makes use of the discovery that, during the relative movement of the oppositely arranged crimping members toward each other and at least partially past each other, and due to the curvature of crimping members, the sausage mixture is initially displaced beyond the actual shape to be produced, namely the round shape of the sausage ends, so that a round shape can form at the sausage end after the mass has relaxed or flowed back. A round portion end can still be formed in an advantageous manner by the curved shape of the crimping members even when the sausage is subjected to cooking after separation and is subject to shrinkage. It is thus possible to produce visually appealing and uniformly formed sausage portions.
- The invention is developed by the curvature being in the form of a convex curvature. The convex curvature preferably extends transversely to the conveying direction across the entire width of the crimping member. The convex curvature has proven to be particularly preferable for forming the round or almost round ends of the sausage portions.
- According to a preferred embodiment, the base portion also has a curvature which is in the form of a convex curvature, in particular. Both the legs and the base portion preferably have a common convex curvature, with the curvatures merging into each other without creases, i.e., in a mathematically continuous manner. In other words, the legs are shaped like a pair of trousers, with the legs being trouser legs, in a sense. The trousers thus have a basic convex shape.
- According to a preferred embodiment, a cutting edge is formed on the inner side of the legs. The cutting edge is preferably designed in such a way the sausage portion can be reliably severed, but without damaging the casing during displacement of the sausage mixture.
- According to a preferred embodiment, the crimping member is made of or consists of one of the following materials: metal, polyoxymethylene (POM). The respective materials have proven to be particularly suitable for forming the crimping members. The materials can be selected, for example, according to the diameter or caliber of the sausages to be processed, or also according to the casing material being used or the thickness of the casing material.
- The invention is developed by the crimping members being oriented relative to the conveyor members in such a way that the crimping members are guided in the conveying area adjacent and parallel to each other. This ensures that the crimping members can be guided parallel to and adjacent each other, despite the conveyor members being arranged so that they move toward each other in the conveying direction.
- According to a preferred embodiment, the conveyor members have receiving elements for receiving the attachment portions of the crimping members. The receiving elements of the conveyor members are designed in such a way that the crimping members can be easily replaced and at the same time form a reliable and durable connection with the conveyor members in operation. In this way, the separator can be easily adapted to different sausage calibers and casing materials, and the crimping members can also be replaced easily in the event of wear.
- According to a preferred embodiment, the curved region has a thickness, viewed in the conveying direction, of 5 mm to 20 mm, and a height, viewed in the conveying direction, of 60 mm, in particular.
- The thickness range of the curved region has proven to be particularly suitable for facilitating the formation of round or almost round portion ends. The thickness in question is to be understood in such a way that the curvature, in particular the convex curvature, has the relevant thickness in the conveying direction or in the opposite direction to the conveying direction, depending on the orientation of the crimping members, and that the curvature extends, in particular, across the entire thickness range of the crimping member.
- The invention is developed by the opening angle of 15° to 120° between the legs. This range of opening angles ensures that the sausage portions are reliably separated and facilitates displacement of the sausage mixture.
- The invention has been described above with reference to a separator. In another embodiment, the invention relates to a crimping member for a separator for separating portions from elongate casings stuffed with food mass, in particular for separating sausages from alginate casings stuffed with sausage meat, said crimping member having an attachment portion for attaching it to a movable conveyor member and a crimping portion arranged adjacent the attachment portion, wherein the crimping portion has two legs that open from a base portion.
- With regard to the crimping member, the invention achieves the object initially specified by the legs being curved on their side facing an adjacently arranged second crimping member in operation, such that the stuffed casing is first constricted in a constriction region with displacement of the mass, and then severed.
- The crimping member is designed in accordance with at least one of the characterizing features of the above embodiments. The crimping member thus utilizes the same advantages and preferred embodiments as the separator according to the invention, and vice versa. Reference is made in this regard to the observations above, the content of which is incorporated here by reference.
- In another embodiment, the invention relates to a method for forming and separating portions from elongate casings stuffed with food mass, in particular for forming and separating sausages from alginate casings stuffed with sausage meat, in which method food mass is stuffed by a stuffing machine into the casing to be stuffed, the stuffed casing is conveyed in a conveying direction by a separator, wherein the stuffed casing is brought between two drivable, circulating conveyor members and is constricted and separated in a constriction region by two adjacently arranged crimping members each arranged on a conveyor member.
- The invention achieves the object initially specified in respect of the method by the crimping members being curved in such a way that the mass is displaced beyond the sausage shape to be produced, so that a round shape is formed at the ends of the sausage portions after the mass has relaxed or flowed back.
- The invention is developed by the separator being designed in accordance with one of the above embodiments. The method utilizes the same advantages and preferred embodiments as the separator according to the invention and the crimping member according to the invention, and vice versa. Reference is made in this regard to the observations above, the content of which is incorporated here by reference.

Portioningdevice 14 then portions the casing 18 stuffed with food mass, for example using pre-crimping members which impinge on the casing and displace both the food mass and casing 18. - Stuffed casings 18, also referred to as
sausage strand 12, then proceed in conveyingdirection 6 to the action range of aseparator 16 which is shown in more detail inFIG. 2 . -
Separator 16 is designed to form sausage portions 10 fromsausage strand 12.Separator 16 has two circulatingconveyor members Conveyor members Conveyor members area 24, which in operation is moved in a conveyingdirection 6. The circulatingconveyor members return area 26. Stuffed casings 18 are introduced between the conveyingareas 24 of the twoconveyor members direction 6.Conveyor members conveyor members area 24decreases conveying direction 6. - Crimping
members 28 are arranged on each ofconveyor member conveyor member members 28 of each one ofconveyor members conveyor members members 28 move toward each other whenconveyor members direction 6. In other words, crimpingmembers 28 are moved parallel to each other and toward each other and at least partially past each other whenconveyor members direction 6. - Crimping
members 28 each have anattachment portion 32 for attaching crimpingmembers 28 toconveyor member portion 34 is arrangedadjacent attachment portion 32. Crimpingmembers 28 are provided with acurvature 40 on a side facing away from the respective adjacently arranged crimpingmember 28. Stuffed casing 18 is first constricted in aconstriction region 30 with displacement of the stuffing mass, and then severed. - Crimping
members 28 are oriented relative toconveyor members members 28 are guided in conveyingarea 24 adjacent and parallel to each other.Conveyor members conveyor belt Conveyor belts toothed belt drive 62. Adeflection region 60 is located between conveyingarea 24 and returnarea 26. -
FIG. 3 shows a detailed view ofseparator 16. As has already been described with reference toFIG. 2 ,conveyor belts toothed belt drive 62. The toothed belt drives 62 that can be seen inFIG. 3 are arranged in the region ofdeflection region 60.Conveyor belts elements 50 in which crimpingmembers 28, inparticular attachment portion 32 of crimpingmembers 28, are arranged. - In the state shown in
FIG. 3 , the crimpingmembers 28 guided oppositely and adjacent each other have already been displaced relative to each other in such a way that only a reduced cross-section remains between the adjacent crimpingmembers 28, in this case an open, diamond-shaped cross-section. In operation, theconstriction region 30 of sausage portion 10 extends through the open cross-section, although this is not shown here. - Due to the further onward movement of crimping
members 28 in conveyingdirection 6, crimpingmembers 28 are moved further relative to each other in the direction of the respective diagonally opposite crimpingmember 28, with the result that the free cross-section is further reduced, and sausage portion 10 is finally separated. Such a state shortly before separation of sausage portion 10 is shown inFIG. 4 . It can also be seen fromFIG. 4 that sausage portion 10 is displaced, beyond the sausage shape to be produced, by the shape of the crimpingmember 28 which is arranged here in the foreground. This causes a rim-shapedsausage end 70 to first be formed. Two sausage portions 10 with such rim-shaped sausage ends 70 are illustrated inFIG. 5 . - As is also shown in
FIG. 6a , the respective rim-shapedsausage end 70 is formed immediately after sausage portion 10 is separated by the crimpingmember 28 according to the invention. However, sausage 10 does not keep the rim-shaped sausage ends 70 that are shown inFIG. 6a and also inFIGS. 4 and 5 , but acquires around sausage end 58 after some time, in particular after the mass inside casing 18 has relaxed or flowed back. In other words, due to the specific shape of crimpingmembers 28, which have acurvature 40 according to the invention, the sausage mixture is first displaced beyond the shape to be produced, namely the round shape, which ultimately results in the round sausage ends 58 being formed after was equalization processes within the mass. - Crimping
members 28 according to the invention shall now be described in more detail with reference toFIGS. 7 to 9 . Crimpingmember 28 has anattachment portion 32 for attaching crimpingmember 28 toconveyor member portion 34 is arrangedadjacent attachment portion 32. Crimpingportion 34 has twolegs base portion 43.Legs curvature 40 on their side which in operation faces away from the adjacently arranged second crimpingmember 28. Due tocurvature 40, stuffed casing 18 is first constricted in aconstriction region 30 with displacement of the mass, and then severed. In this case,curvature 40 takes the form of a convex curvature 42.Base portion 43 likewise has a curvature which is in the form of a convex curvature, in particular. - A
cutting edge 46 is formed on the inner sides oflegs 39.Curved region 40 has athickness 52 in conveyingdirection 6.Legs opening angle 54.Transition 56 between the curvature ofbase portion 43 and thecurvature 40 oflegs - The embodiments described above are only descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Various variations and modifications can be made to the technical solution of the present invention by those of ordinary skills in the art, without departing from the design and spirit of the present invention.
